Dib u eegis kooban oo ku saabsan Lithium Niobate Crystal iyo Codsiyada - Qaybta 7: Dielectric Superlatice ee LN Crystal

Sannadkii 1962, Armstrong et al.marka hore waxay soo jeedisay fikradda QPM (Quasi-phase-match), kaas oo adeegsada vector-ka rogan ee ay bixiso superlatice si loo magdhaboplaakiin is-waafajin la'aanta habka is-barbardhigga indhaha.Jihada polarization ee ferroelectricssaamayns heerka polarization aan toos ahayn χ2. QPM waxa lagu xaqiijin karaa iyada oo la diyaariyo qaab-dhismeedyada xayndaabyada ferroelectric oo leh jihooyin kala duwan oo xilliyeed ah oo ka soo horjeeda hay'adaha ferroelectric, oo ay ku jiraan lithium niobate, lithium tantalate, iyoKTPcrystals.crystal LN waa kanugu ballaaranloo isticmaalomaaddogoobtan.

Sannadkii 1969kii, Camlibel waxa uu soo jeediyay in qaybta ferroelectric eeLNiyo kiristaalo kale oo ferroelectric ah ayaa dib loo rogi karaa iyadoo la isticmaalayo garoon koronto oo sarreeya oo ka sarreeya 30 kV/mm.Si kastaba ha ahaatee, garoon koronto oo sidaas u sarreeya ayaa si fudud u daloolin kara crystal-ka.Waqtigaas, way adkeyd in la diyaariyo qaab dhismeedka korantada wanaagsan oo si sax ah loo xakameeyo habka dib u celinta polarization domain.Wixii markaas ka dambeeyay, waxaa la isku dayay in la dhiso qaab dhismeedka domain-ka badan iyadoo la bedelayo laminationLNcrystals ee jihooyin kala duwan, laakiin tirada chips in la xaqiijin karaa waa xaddidan.Sannadkii 1980-kii, Feng et al.kiristaalo la helay qaab dhismeedka polarization xilliyeed iyadoo loo eegayo habka kobaca eccentric iyadoo la eexanayo xarunta wareegtada crystal iyo goobta kulaylka ee axis-symmetric center, waxayna xaqiiqsadeen soo noqnoqda labanlaabmaya soosaarka 1.06 μm laser, kaas oo xaqiijiyayQPMaragti.Laakiin habkani wuxuu leeyahay dhib weyn oo ku saabsan xakamaynta wanaagsan ee qaab-dhismeedka xilliyeed.Sannadkii 1993, Yamada et al.waxay si guul leh u xalliyeen habsocodka rogaal-celinta polarization-ka xilliyeedka iyadoo la isku darayo habka lithography semiconductor iyo habka goobta korontada ee la dabaqay.Habka polarization field koronto ee la dabaqay ayaa si tartiib tartiib ah u noqday tignoolajiyada diyaarinta guud ee xilliyeedkaLNcrystal.Waqtigan xaadirka ah, xilli-xilliyeedkaLNcrystal ayaa la ganacsiyeeyay oo dhumucdiisuna way kartaabein ka badan 5 mm.

Codsiga bilowga ah ee poled periodicLNcrystal waxaa inta badan loo arkaa beddelka soo noqnoqda laser.Horraantii 1989, Ming et al.waxay soo jeedisay fikradda ah superlatices dielectric oo ku salaysan meelaha sare ee laga dhisay qaybaha ferroelectricLNcrystals.Lattice rogan ee superlatice ayaa ka qayb qaadan doona kicinta iyo faafinta hirarka iftiinka iyo dhawaaqa.Sannadkii 1990-kii, Feng iyo Zhu et al.wuxuu soo jeediyay aragtida is-barbar-dhigga quasi-ga badan.Sannadkii 1995, Zhu et al.loo diyaariyey qalab-xilliyeedka sare-sare ee dielectric iyadoo la adeegsanayo farsamada polarization heerkulka qolka.Sannadkii 1997, xaqiijinta tijaabada ah ayaa la sameeyay, iyo isku dhafka wax ku oolka ah ee laba hab oo is-eegis ah-labanlaabida soo noqnoqda iyo isu-ururinta soo noqnoqoshada ayaa lagu xaqiiqsaday si heer sare ah, sidaas awgeed waxa la gaadhay laysar wax ku ool ah oo saddex jibbaaran labanlaabmay markii ugu horeysay.Sannadkii 2001, Liu et al.loogu talagalay qorshe lagu xaqiijinayo leysarka saddex-midab leh ee ku saleysan is-waafajinta wejiga.Sannadkii 2004, Zhu et al waxay xaqiiqsadeen naqshadaynta muraayadda indhaha ee wax-soo-saarka laser-mawjadaha-mawjadaha badan iyo codsigeeda dhammaan laser-goboleedyada.Sannadkii 2014, Jin et al.nashqadeeyay qalab sare oo indhaha ah oo isku dhafan oo sawir qaade ah oo ku salaysan dib u habeynLNJidka indhaha ee waveguide (sida ku cad shaxanka), gaaritaanka jiil hufan oo sawir-qaadis ah iyo hab-habayn koronto-optic oo xawaare sare leh oo ku saabsan chip-ka markii ugu horreysay.2018, Wei et al iyo Xu et al waxay diyaariyeen qaabab domain xilliyeed 3D oo ku saleysanLNkiristaalo, oo la xaqiiqsaday qaabaynta alwaax aan toos ahayn oo hufan iyadoo la adeegsanayo qaab-dhismeedka domain xilliyeed ee 3D sanadka 2019.

Horumarinta aragtida superlatice dielectric ayaa kor u qaaday codsigaLNcrystals iyo kiristaalo kale oo ferroelectric ilaa dherer cusub, oo la siiyeyRajada codsiga muhiimka ah ee dhammaan lasers-gobolka adag, shanlada inta jeer ee indhaha, cadaadiska garaaca wadnaha laser, qaabeynta iftiinka iyo ilo iftiin ah oo isku xiran ee isgaarsiinta quantum.
